czm_encodedCameraPositionMCLow
An automatic GLSL uniform representing the low bits of the camera position in model
coordinates. This is used for GPU RTE to eliminate jittering artifacts when rendering
as described in Precisions, Precisions.
Like all automatic uniforms, czm_encodedCameraPositionMCHigh does not need to be explicitly declared.
However, it can be explicitly declared when a shader is also used by other applications such
as a third-party authoring tool.
Example
// GLSL declaration uniform vec3 czm_encodedCameraPositionMCLow;
